Banner for Nutrient Application Ban

CAAR advises all Manitoba members and producers information regarding restrictions on winter nutrient application from the Manitoba Agriculture and Resource Development website.

Nutrient Application Ban in Effect for Manitoba

The Government of Manitoba - Agriculture and Resource Development: Through private and public stakeholder consultations, they have determined not to implement a variance to the winter nutrient application restrictions effective November 10, 2020. 

No provincial variance in effect. Nutrients cannot be applied on or after November 10, 2020.

Below normal daytime highs and overnight low temperatures are deemed to create unfavorable conditions increasing potential nutrient losses to the environment. Farmers and ag retailers are encouraged to review the Nutrient Management Regulation link below.

Farmers may apply for individual variances under extenuating circumstances. The department will continue to monitor environmental conditions. In the likelihood of the return of favorable temperatures, a variance to open further nutrient applications may be considered.

Restriction on Winter Application of Nutrients

Provincial legislation prohibits the application of nitrogen and phosphorus between and including November 10th of one year and April 10th of the following year. Nutrient sources containing nitrogen and/or phosphorus include synthetic fertilizer and livestock manure. The winter spreading restrictions are in place as the application of nutrients onto frozen or snow-covered soils results in an increased risk of nutrient runoff. Nutrient runoff to waterways contributes directly to algal blooms in Lake Winnipeg and elsewhere.

However, there may be some years where weather conditions are such that agricultural land can reasonably be worked to apply nutrients between November 10th of one year and April 10th of the following year for crop uptake while still protecting water quality. In these cases, a provincial or regional variance may be issued.
